For such applications, the antenna arms need to be resistively loaded for radiating and sensing nondispersive pulses. Compared to conventional subtractive process and subsequent surface-mount techniques utilized based on printed circuit boards (PCBs), printed electronics is an additive process that ensures the mechanical stability of the antenna and remarkably reduces the time, cost, and waste for fabrication. For the resistive loading based on printing technology, CNTs are used as the resistive printing material in this research. In the proposed CNT-printed RVD, the antenna arm is divided equally into eight segments for discrete loading, where each segment contains both conductor and resistor areas for printing silver paste and CNT inks, respectively. To use the CNT inks, a multiwalled CNT (MWCNT) is synthesized by a catalyst chemical vapor deposition (CCVD), and the chemical properties of the synthesized powders are measured. During fabrication, the area for the silver ink is first printed using a screen-printing process, whereas the printing of the MWCNT is subsequently performed using a spray deposition technique. The structural properties of the printed inks are investigated using scanning electron microscopy (SEM). Finally, the performance of the CNT-printed RVD is validated through antenna measurements and a series of experiments. Because the fabricated antenna shows excellent performance for pulse radiation and sensing, the proposed realization method may be regarded as a promising replacement for existing processes based on PCBs.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"19125-19137"},"PeriodicalIF":4.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EMR monitoring method for concrete cracking is a noncontact and nondestructive monitoring approach. However, substantial interference from environmental EMR noise degrades the consistency of monitoring signals, resulting in low recognition accuracy and a limited monitoring range. To address this, this study introduces a resonance noise reduction method based on the structure of EMR monitoring sensors. The proposed approach enhances the clarity and interpretability of monitored EMR signals through frequency-domain amplitude transformation and discrete wavelet decomposition. The time–frequency characteristics of both EMR signals and noise are comprehensively analyzed by utilizing continuous wavelet transform. A parallel network architecture integrating a convolutional neural network (CNN) and long short-term memory (LSTM) is employed to extract features from EMR signals associated with concrete cracking. Additionally, multiscale convolutional kernels and attention mechanisms (AMs) are integrated according to the time–frequency characteristics of the signals. Experimental results reveal that the proposed method effectively distinguishes EMR signals from four common types of EMR noise, achieving an average signal recognition accuracy of over 98% on the validation and test datasets, with a crack identification accuracy rate of 94.6%. This approach significantly enhances the applicability and potential use of EMR monitoring in concrete cracking scenarios.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20238-20249"},"PeriodicalIF":4.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, flight data anomaly detection is crucial for aviation safety, enabling the identification of deviations from normal operations. However, due to the complexity and high dimensionality of the flight data, existing methods often fail to adequately extract temporal and variable information. As a result, these methods exhibit poor detection performance, especially when the anomaly data is scarce. To address these issues, we propose a novel dual-view graph attention network (DGAN) model for flight data anomaly detection. Specifically, two parallel graph attention (GAT) layers are employed to create embeddings that are rich in temporal correlations and variable dependencies. A TCN-based autoencoder module is proposed for data augmentation on these embeddings to extract two views consistent with the underlying data patterns. Furthermore, DGAN constructs pairs of positive and negative samples both within a single view and between different views. A dual-view contrastive training strategy is proposed to construct contrastive loss, which can learn a good representation of the flight sequence and ensure effective anomaly detection even in cases of scarce anomaly data. We conduct experiments on a dataset comprising 44808 real-world flight samples from the Airbus A321. The results demonstrate that the performance of DGAN exceeds state-of-the-art (SOTA) models. Moreover, we examine the effectiveness of DGAN through further visualizations and case studies.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20956-20969"},"PeriodicalIF":4.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, oxygen vacancy defects within the material limit its further enhancement of optoelectronic performance. Current research primarily focuses on doping modifications to improve the properties of Ga2O3, because the doping concentration significantly influences the performance of films. In this work, magnesium (Mg) doping was introduced to enhance the optoelectronic properties of Ga2O3 films. Mg-doped Ga2O3 (MgGaO) films were fabricated using plasma-enhanced atomic layer deposition (PEALD) through adjusting the magnesium oxide (MgO) cycle ratio. The structural, chemical, morphological, and optical properties of MgGaO films were analyzed using X-ray diffraction, X-ray photoelectron spectroscopy, atomic force microscopy, scanning electron microscopy, and ultraviolet-visible spectroscopy. The results indicate that as the MgO cycle ratio increases, the crystallinity and surface roughness of MgGaO films improve, and the optical bandgap increases from 4.84 to 5.91 eV. The oxygen vacancy content in the films decreases initially but increases at higher MgO cycle ratios. Additionally, the films with different MgO cycle ratios were applied to fabricate solar-blind photodetectors. The photodetector demonstrated the best performance at an MgO cycle ratio of 5%, exhibiting a dark current as low as <inline-formula> <tex-math>$4.90times 10^{-{15}}$ </tex-math></inline-formula> A, an ultrahigh photocurrent-to-dark current ratio of <inline-formula> <tex-math>$9.70times 10^{{6}}$ </tex-math></inline-formula>, and rise/decay times of 74.7/45.7 ms, with the highest responsivity of 13.2 mA/W in the 200–280 nm range.

In particular, it is well-known that wideband signals can be obtained using composite multisine signals. However, the choice of the frequencies and/or phase shifts in these sinusoids is critical to approach a flat power spectrum with a low crest factor. A number of known methods, such as using Rudin-Shapiro polynomials or random phases, have been used in this problem. However, the use of Egyptian fractions has not been explored yet, despite being easier to generate and implement. Here, we construct multisine signals (in the form of a voltage) based on different Egyptian fraction sequences (EFSs) and use them to measure the linear time-invariant impedance of an RC circuit and then the instantaneous impedance of nonlinear time-varying solar cell. Two methods are used to generate these signals: 1) the EFSs are assigned to the phase angles or 2) they are used to set the values of the angular frequencies. The accuracy of measurements is assessed via comparison to the standard sine-sweep method using a research-grade Biologic VSP-300 electrochemical station showing acceptable results.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"19555-19562"},"PeriodicalIF":4.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By analyzing surface electromyographic (EMG) signals, lumbar movements can be recognized, enabling real-time feedback for personalized training. Deep learning methods are increasingly used to recognize these movements. Conventional deep learning models only capture local spatial information and deep features during the feature extraction process, which limits their ability to extract global temporal dependence features and shallow features. Furthermore, their capability to capture the global contextual information is also relatively restricted. To this end, this article presents a new model that integrates the global–local feature extraction (GLFE) block, the contextual transformer (CoT) block, and a modified backbone architecture of DenseNet: the global and local contextual information integrated denseNet (GLCII-DenseNet) model, designed for the recognition of sparse surface EMG signals from the waist. This model extracts rich shallow, deep, local, and global features, enhancing its capability for feature representation and context feature information capture. It effectively integrates feature information from different locations while extracting a large amount of feature data, thereby improving the accuracy and robustness of EMG signal recognition. To verify the practical validity of the model, we recorded ten healthy subjects, each of whom extracted EMG signals from four muscles while performing six common lumbar exercises. Comparison experiments with other networks show that the model outperforms other methods in recognizing sparse surface EMG signals. In addition, we conducted model generalization comparison experiments to further evaluate the model’s performance. The results show that our model is more robust to noise interference.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20158-20168"},"PeriodicalIF":4.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elbow joint impairments can be brought on by aging, accidents, and repetitive motions making the monitoring of elbow angles critical. In this work, a sensor for elbow angle monitoring during bending and extension using a fiber Bragg grating (FBG) embedded in polydimethylsiloxane (PDMS) with a wearable band is proposed. Two methods for measuring elbow angles, wearable and platform-based sensing are investigated. The wearable sensor-based measurements are consistent over different trials with a linear variation of Bragg wavelength with flexion/extension angle up to 90°. The sensitivities for flexion and extension are 0.0029 and 0.0037 nm/°, respectively. Further, the factors contributing to error in the measurement of elbow angle such as tightness of wearable band, spatial and angular misalignment of the sensor, and the removal and replacement of sensor are studied. The findings show that the error is maximum for an angular misalignment followed by tightly bound sensor and spatial misalignment. The desirable configuration for elbow angle measurement is a tightly bound sensor at the mean position for high mean sensitivity with a tolerable level of error and a left/right-aligned sensor with moderate tightness for minimum error at a low sensitivity. The PDMS-embedded FBG-based wearable sensor, in an optimal configuration, can be used for monitoring elbow angles.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"19341-19348"},"PeriodicalIF":4.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
